Although not yet available to consumers, 38 high-end smartphones from Samsung, LG, Xiaomi, Asus, Nexus, Oppo and Lenovo have pre-installed malware stealing personal data, according to information from technology company Check Point.
Among the 38 smartphones detected with pre-installed malware, there are popular smartphones such as: Galaxy Note 2, LG G4, Galaxy S7, Galaxy S4, Galaxy Note 4, Galaxy Note 5, Galaxy Note 8, Xiaomi Mi 4i, Galaxy A5, ZTE x500, Galaxy Note 3, Galaxy Note Edge, Galaxy Tab S2, Galaxy Tab 2, Oppo N3, Vivo X6 plus, Nexus 5, Nexus 5X, Asus Zenfone 2, Lenovo S90, OppoR7 plus, Xiaomi Redmi and Lenovo A850.
According to Check Point, all of these high-end smartphones are distributed by two (unidentified) companies, including a large telecommunications company and a multinational technology company.
Through testing, the malware was not pre-installed on the ROM, but was installed during the process from when the device shipped and transferred to these two distribution companies.
The smartphone samples tested to be infected with 2 malware are Loki and SLocker, notably these 2 malware are integrated deep inside the system and have the ability to root deeply on the device.
Loki collects and steals information about application lists, web browsing history, contacts, call logs and current location data. It was first discovered in February 2016. SLocker is a ransomware malware that specializes in encrypting data and files to prevent the device from working, thereby blackmailing users through the anonymous Tor browser.
When you know this information, a question that many users wonder is whether or not to remove this malware from the phone. According to Check Point, once malware has gained root access to the device, it is very difficult to completely remove it. Users can only restore factory settings or run a brand new ROM.
This is not the first time a smartphone has been preinstalled with malware. In November 2016, researchers discovered a kind of backdoor hidden in firmware developed by AdUps (China) on more than 700 million middle-class Android smartphones and tablets, the software also secretly collect data and send it back to the server in China.
Filter system of 2,000 liters of water / day by solar energy
Tenkiv Nexus’s renewable energy system can use solar heat to generate energy at “only one-tenth the cost of solar panels and one-fifth the cost of fossil fuels.”
Tenkiv, a startup company in Sacaramento, California, recently created a unique energy regeneration system. This system can initially be applied in water filtration in areas such as Asia and Africa, expected capacity up to 2,000 liters / day.
Tenkiv’s long-term goal is to “access water and sustainable energy” through its modular system. It will not only produce energy from solar heat for low-cost water filtration, but also store, distribute and convert solar energy for use in Other applications, especially in areas where infrastructure is poor or even unavailable.
Instead of focusing on photovoltaic technology that converts sunlight into electricity, which is used in most solar systems today, Tenkiv opted to build its own system, which uses Solar energy is the source of energy.
One of the reasons Tenkiv chose to use solar heat over photovoltaic technology is because it does not require the conversion of the sun’s heat to other forms of energy, such as electricity, which can cause energy loss during metabolism.
According to Tenkiv, its technology could power other applications with “the price is only 1/13 the price of solar panels currently in use and 1/5 the price of fossil fuels,” This will create momentum for the company to expand the water filtration system to meet the needs of about 1 billion people who do not have access to clean water regularly.
The entire system also has very few moving parts (the thermal plate itself is also fixed), which means it will have a long life and low maintenance costs. In addition, by allowing the use of direct heat or conversion into electricity, this system is more flexible and efficient than the photovoltaic system.
Tenkiv said: “The Tenkiv solar collector can distribute the heat collected from the sun quickly and efficiently. Whether heating water for bathing or boiling tea or cooking noodles are the same, all these processes require energy. The energy used in most modern systems is provided by a complex and inefficient chain, because they take energy to create energy. With Tenkiv Nexus, we take heat directly from the sun without consuming any finite power. ”
The company added: “By using proprietary PII thermo-circuits on the modules, we have broken the high price barrier for the energy used to remove viruses, bacteria and parasites from water. . Tenkiv’s advanced technology provides a practical, affordable solution to bring clean water and renewable energy to communities around the world, thereby preventing pathogens from water. ”
The company is also currently working on building a “smart automation building that can produce more energy than the energy it uses” taking the Tenkiv Nexus system as its core. This really means a great deal for the future development of commercial and residential buildings.
